It is better not have loved and lost then never to have or something like that
Probly for the best anyways!!! Good luck with the next one.
Always do a Revs check when buying a used car, boat, or caravan. Be it privately or even from a dealer. The repairable write off thing is one issue you may uncover, but also more commonly, You might uncover that there is money owed on the vehicle. Which can lead to some finance company coming to repossess your boat because some other guy hasn’t paid his loan. And guess what they can and will do it.
ALSO never ever buy a boat from this guy I have made that mistake twice now
